”The year is in spring”, spring everything is revived, vibrant, but there are some children are always listless, sleepy and sleepy, is it “spring sleepiness” or disease? Spring sleepiness is a physiological reaction to the change of seasons. After entering spring, as the temperature rises, the peripheral blood vessels of the human body are stretched, the blood supplied to the brain is relatively reduced, and the brain function is inhibited, so you will feel that you can’t sleep enough. However, it is worth noting that “spring sleepiness” is often a manifestation of some diseases, especially when uncontrollable “sleep” occurs, such as in class, at work, or even when driving suddenly into a sleep state, it is likely to be a disease –Episodic Sleeping Disorder. Episodic sleep disorder is a sleep-wake disorder that is characterized by recurrent episodes of irresistible sleep attacks during the day. It usually begins in childhood or adolescence, but can also occur in adults. Most children have typical clinical manifestations: excessive daytime sleepiness is the first symptom of episodic sleep disorder: children often suddenly fall asleep during classes, meals, homework, watching TV, and are not easily woken up; sudden collapse episodes are also frequent symptoms, manifested by sudden facial expressions of dullness or head bowing, knee bending, or even general weakness and fall down during emotional excitement, such as laughing, crying, or intense activity (as the saying goes) “Sleep hallucinations often occur before going to sleep or after waking up, and children often complain of scary dreams and emotional experiences; sleep paralysis is manifested by a brief period of immobility and inability to speak when falling asleep or waking up. In addition, the child has restless sleep at night, wakes up easily, and turns over with increased leg movements; the child is emotionally unstable and loves to lose his temper. The cause of episodic sleep disorder is still unclear and may be related to genetic and environmental factors and certain central neuropathies. The diagnosis is based on the clinical presentation of the child and the results of polysomnography monitoring. Blood, electroencephalography and cerebrospinal fluid tests can also be used to assist in the diagnosis. Many advances have been made in the treatment of episodic sleep disorders, and studies have found a close correlation between abnormalities in the function of Orexin neurons in the central nervous system and the disorder. Foreign studies have revealed that a multi-receptor target drug can be used to treat episodic sleepiness, with significant improvements in daytime sleepiness, sudden collapse episodes, sleep paralysis and nighttime sleep, and more and more studies suggest that the drug has a pro-neurodevelopmental and growth effect. In addition to medication, parents should arrange the child’s rest time reasonably to ensure sufficient sleep at night and appropriate naps during the day, which is also very important for the relief of the disease.
